The solubility, heats of solutinn in poly (ethylene terephthalate) and solvents such as hexane, cyclohexane, perchloroethylene and water have been investigated for disperse dye, C. I. Disperse Violet 1. The resultant values were applid to regular solution theory concerning solution parameter concept. The results obtained are as follows. The dye solubility in the solvent is higher in the order of the large difference in dye and solvent solubility parameters, but the heat of solution is adversely. The equilibrium up-take for dye is higher in the order of the large difference in solvent and poly (ethylene terephthalate) solubility parameter.

Purpose: To evaluate retrospectively whether it is possible to predict the transarterial chemoembolization(TACE) result with the pre-TACE dynamic CT findings. Materials and Methods: The dynamic CT findings of 33 patients with 35 nodular and 8 massive hepatocellular carcinoma(HCCs) who was taken follow up CT after TACE, were reviewed retrospectively. After excluding the diffuse or infiltrative HCCs, the mass was classified into two groups of nodular and massive types. The size, location, degree of enhancement, pseudocapsule, portal vein(PV) thrombosis and arterioportal(AP) shunt were evaluated on the dynamic CT scans. The vascularity, multiple or parasitic blood supply, AP shunt and the possibility of superselection were considered on the angiography. After TACE, the pattern of lipiodol uptake and residual enhancing nodules were evaluated on the follow-up CT scans. Results: The good TACE results could be obtained in 18 of 35 nodular HCCs with dynamic CT findings of small size(mean=2.94cm), peripheral location, hyper-or iso-enhancement, and absence fo PV thrombosis, with angiographic finding of possible superselection, but the pseudocapsule did not give important effect on the result. Most of the massive HCCs had poor TACE results. Conclusion: The prediction of the TACE results of nodular and massive HCCs was possible with dynamic CT findings. If the good prognostic factors were not observed on the pre-TACE dynamic CT, the multiple TACE and/or combination therapy with percutaneous ethanol injection(PEI), surgical resection or others should be considered for the effective control of the HCCs.

The LoCation Services (LCS) feature in W-CDMA(Wideband CDMA) network provides the mechanisms to support mobile location services for operators, subscribers and third part service providers. The existing location positioning method are classified into the cell ID based, OTDOA, and network assisted GPS. A new hybrid location positioning method which combines three of these methods are proposed. We present the LCS funcition and system design using SDL (Specification and Description Language) and SDL development tool (SDT). This design covers the LCS functional model and signalling procedure, system architecture, data structrue, and process SDL diagram.

Background: Predicting outcome after head trauma is of great interest for clinicians, especially in the early stage. It may provide a basis for therapeutic strategies and may be helpful to select different approaches. But, reliable outcome prediction from head trauma is still unresolved. The purpose of this study is to determine which clinical parameters can be used effectively after an event of head trauma. Methods: In our study we studied head trauma patients who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of June 1998 to 31th of January 2000, looked into medical records, and studied the records in a retrospective manner. The head trauma patients were divied into two group, a) favourable outcome-related and b) unfavourable outcome-related. The two groups were then subdivided according to their sex, age, the mechanism of their injury, the time they came in, alcohol drinking, loss of consciousness, vomiting, pupil change, previous medical illness, associated injuries and were seperately compared and analyzed. And the factors affecting Glasgow Outcome Scale(GOS) were analyzed in the parameters of Injury Severity Score(ISS), Revised Trauma Score(RTS), Glasgow Coma Scale(GCS), motor score of GCS(mGCS), Marshall Computed Tomographic Classification(MCTC). Statistically, t-test and Mann-Whistney rank sum test using Jandel-sigma were used in the study and then were assessed in Chi-square analysis methods. The statistical significance was determined at a level of p less than 0.05. Results: The total of the head trauma patients, added up to 129 people, 99:males and 30:females. Among this sum, 99 patients showed a favourable outcome and 30 patients showed an unfavourable outcome at discharge. The causes of injury included: automobile accident in 42 cases; fallss in 26; assaults in 6; and accidental-slipping injury etc in 55 cases. 12 patients had bilateral unreactive pupils on admission, 2 had unilateral reactive pupils, and 113 had bilateral reactive pupils. Compared to the favourable outcome-related head trauma group, the unfavourable outcome-relared head trauma group had more history of loss of consciousness, unreactive pupils and tended to have previous medical illness. There were no difference in alcohol related, vomiting and associated injuries between two groups(favourable outcome-related head trauma group: unfavourable outcome-related head trauma group). Substantial difference were observed in GCS, mGCS, ISS, RTS, MCTC between two groups. Patients with unfavourable outcome had a significantly higher ISS, lower RTS, lower mGCS. After MCTC, patients with mass lesion had unfavourable outcome than patients with diffuse injury. Conclusion: Age, history of loss of consciousness, previous medical illness and unreactive pupil change are predictives of outcomes of head trauma patients with respect to Glasgow outcome scale. The lower GCS, lower RTS, lower mGCS, higher ISS, mass lesion based on CT scan provide poorer prognostic outcome in patients with head trauma. Use of prognostic factors thorough complete history taking and physical examination would provide useful prognostic information and facilitate improved therapeutic decision-malting in head-injuried patients.

Literally, the mean of Tae-gye is highest brook. And on the basis of the acupuncture theory, Tae-gye point is the Soo earth point and source point of the Kidney Channel as well. In addition, Tae-gye point is one of the Yang-Returning Nine points. We were trying to study bibliographically on the Tae-gye point because Tae-gye point can be used very broadly across the symptoms in the theoretical aspect described above. As a results, we found out that according to the classical books of acupuncture, Tae-gye point is entering point of the Meridian Water as a source point and can be used at both Kidney-Sufficient Syndrom and Kidney-Deficient Syndrom. And Tae-gye can be applied to the disease of kidney or bladder that is urogenital symtoms, Also, Tae-gye is an useful option of tooth-ache, asthma, indigestion, constipation, edema etc whose cause is related with decrease of Kidney ki.

Background: We studied the incidence of trauma caused by alcohol related accidents, and the effects that alcohol has on the occurrence, the extent, and the outcome to the patient. Methods: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of January 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were devided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analyzed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. Results: The total of the trauma patients, added up to 832 people, 577:male and 255:female. Among this sum, 163 trauma patients were alcohol related(male:127 & female:36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mostly by fist-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer to the alcohol-related trauma patients. Conclusion: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time and the reason for their visit were mostly because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.

Biodegradation of Gas-phase Styrene in a High-performance Biotrickling Filter using Porous Polyurethane Foam as a Packing Medium

Moon, Cheul-Hyun,Lee, Eun-Yeol,Park, Sung-Hoon 한국생물공학회 2010 Biotechnology and Bioprocess Engineering Vol.15 No.3

A biotrickling filter (BTF) packed with porous polyurethane (PU) foam sheets was developed and operated for removal of gas-phase styrene. The specific surface area and void fraction of the PU foam sheet were determined to be 497 $m^2/m^3$ and 0.92, respectively, by using mathematical modeling and experimental measurement. The effects of gas flow direction (co-current and counter-current), styrene loading rate and empty bed residence time on the efficiency of the BTF were analyzed. The BTF achieved a high elimination capacity of 4.0 ~ 5.0 kg styrene/$m^3$day due to the high specific surface area of the PU foam. The BTF could be operated repeatedly when excessively-grown biomass was periodically removed, using circulating NaOH solution for 2 h every four days.

Byeong-Cheul Moon,Sung-Tae Park,Soon-Chul Kim,Suk-Ju Kwon,Andrew Martin Mortimer,Collin Piggin 韓國作物學會 1999 Korean journal of crop science Vol.44 No.1

The experiment was conducted to investigate emergence response of lowland weeds at different soil moisture contents, burying depths and upon changes in soil moisture. Rice germination was over 50% at all burying depths under aerobic condition, but the emergence rate of the soil surface placed seeds in saturated and flooded conditions decreased by 19% and 29%, respectively, as compared with that of aerobic condition. Rice seeds at burying depth of over 3 cm did not emerge at all. The emergence rate of Echinochloa crus-galli (L.) Beauv. in aerobic condition was lower than 30%, but the emergence pattern of E. crus galli (L.) Beauv. at different soil moisture contents and seeding depths was similar to that of rice. Emergence behavior of lschaemum rugosum Salisb., Ludwigia octovalvis (Jacq.) Raven and Sphenoclea zeylanica Gaertn. which are dominant lowland weed species in the Philippines also differed depending on soil moisture conditions and burying depths. lschaemum rugosum Salisb. emerged at all burying depths under aerobic condition, whereasLudwigia octovalvis (Jacq.) Raven emerged only at 0 cm deep under saturated and aerobic condition and Sphenoclea zeylanica Gaertn. at 0 cm deep under flooding condition. Weed seeds planted at 1, 3, and 5 cm deep in continuous flooded and saturated condition did not emerge at all, but upon a change of soil moisture condition from saturated to drainage (S~rightarrow D) and flooded to drainage (F~rightarrow D), grass weeds began to germinate again and the average emergence rate in S~rightarrow D and F~rightarrow D were 26% and 5% forE. crus-galIi (L.) Beauv., 9% and 8% forI. rugosum SaIisb., respectively. Weed seeds buried in soil in the pot showed great emergence at S~rightarrow D but did not emerge under continuous flooded condition. The diversity index accounting for dominance degree and occurrence aspect of weed, was the lowest at F~rightarrow D.

논문 : 한인의 단동 이주와 생활

문종철 ( Jong Cheul Moon ) 단국사학회 2012 史學志 Vol.45 No.-

단동의 역사와 지리 위치는 우리 민족 연구사에서 중요한 위치를 차지하고 있다. 이러한 단동지구 한인의 이주, 경제활동, 독립운동, 교육상황을 살펴보자면 다음과 같다. 단동지구에는 수·당시기부터 한인들이 살아온 기록이 보이고 있으며 이 지역과 인접한 평안도에서 대다수가 이주하였다. 한인들은 생계를 유지하기 위하여 단동 변경지대에 들어와서 황무지를 개간하여 농사를 짓고 거주하였다. 1910년 일본제국주의가 조선반도를 점거하자, 지식분자와 애국자들은 단동지구에 이주하여 반일활동을 진행하였다. 이후 단동지구의 한인은 중국 군벌통치자들의 배척정책, 9·18사변 이후 이지역의 관리 소홀, 1945년 광복과 중화인민공화국의 성립으로 인구증감을 겪었다. 현재 단동지구에는 중국의 개혁개방 정책이 진행됨에 따라 조선족 인구가 지속적으로 늘어나고 있다. 단동지구에 이주한 한인들의 경제활동은 농업을 주로 하면서 공상업에도 종사하였다. 한인 인구의 대다수는 벼농사를 하여 신해혁명 후에는 대규모로 수전 개발을 이루었고, 공업은 주로 가장 번창한 정미소를 비롯하여 운송 목재가공, 종이상자 등의 공장이 있었다. 그러나 일본제국주의의 동북지구 약탈로 각종 세와 비용을 납부하게 되자 생활에 어려움을 겪었다. 단동지구의 조선족들은 광복 이후 공산당의 영도하에 토지개혁이 시작되면서 자기의 토지를 얻게 되었다. 조선족 공상업자들은 조선반도로 이주하거나 단동지구에 남아서 국가 집체기업의 노동자로 되었고 이후 중국의 개혁개방 정책을 실시하면서부터 단동지구에는 조선족의 공상기업이 나타났다. 단동지구 한인의 독립운동은 주로 관전현 산악지역에서 전개되었다. 1896년 의병의 반일투쟁이 조선봉건정부와 일본제국주의의 진압으로 인해 불가피하게 중국 동북지역으로 이주 하게 되었다. 한인들은 1910년 한일합병 이후 지속적으로 반일단체를 결성하여 관전현의 향로구, 홍통구, 하로하 등의 지방에서 반일 투쟁을 진행하였다. 대표적으로 대한청년연합회, 광한단, 조선의용대, 광복군사령부, 광복군총영, 통군부, 정의부, 조선혁명군, 항일연군 등의 단체가 단동지구에서 활동을 하였다. 단동지구의 한인 교육체계는 소학교, 초등중학교, 고등중학교, 성인교육으로 조성되었다. 한인 소학교와 중학교 교육은 민국초기부터 관전, 봉성, 안동 등 한인이 집중 거주하는 곳에 설립되었다. 수업과정은 일본의 점차 영향을 많이 받게 되었다. 성인 교육은 20년대에 조선 독립군이 야학을 세워 글과 독립 사상을 선전하면서 시작되었다. 문화 대혁명이 끝난 후의 단동지구에서는 일관제 기숙학교가 시행되고 조선족 중학교를 건립되었으며 신문과 성인 대학을 통해 성인교육의 수준을 향상시키고 있다. The history and the geographical location of Dandong(丹東) have a important position in the history of Korean national studies. Examined Korean`s migration, economic activities, independence movements and educational situation in Dandong area are as follows: There are documents that show Korean has been living in Dandong province since Sui(隨) and Tang(唐) China, also the most Korean migrants are from Pyeongan-do province which is adjacent to Dandong. Korean migrants came into the borderland, developed the wild land, and lived by cultivating to support their living. When Imperial Japan occupied Korea in 1910, Korean intellectuals and patriots moved in and, proceeded to anti-Japanese movements. After this, Korean in Dandong experienced population curves with the exclusion policy by Chinese warlords, carelessness after Manchurian Incident(滿洲事變), the Independence in 1945 and the establishment of new China(People`s Republic of China). Now Korean population in Dandong has increased by progressing with Chinese reform-opening policy. Korean migrants in Dandong had economic activities in mainly agriculture as well as commerce and industry. The most migrants were engaged in rice farming, so that they developed paddy fields on a large scale after Xinhai Revolution(辛亥革命). In industry, they managed not only rice mills―the most prosperous― but also timber processing, paper box manufacture and other factories. However, plundered by Imperial Japan the migrants had to pay taxes and expenses of all sorts, and were in hardship in living as the result. After the Independence, as the land reform began under the leadership of Chinese communist party, Korean in Dandong obtained their own land. Korean merchants and industrialists, in addition, migrated to the Korean Peninsula, otherwise became workers for township and village enterprises(鄕鎭企業) in Dandong. Korean own businesses were shown from having Chinese reform-opening policy begun. Korean independence movements in Dandong were mostly developed in the mountain regions of Kuandian(寬甸) province. Because of the suppression by the feudal government of Joseon and Imperial Japan in 1896, the anti-Japanese struggles of Korean righteous armies had to move to Northeast China. Since Korea-Japan Annexation(韓日合倂) in 1910, Korean had continually formed the anti-Japanese organisations, and had made the struggles in progress in Xianglu(香爐溝), Hongtong(紅 通溝) and Xialuhe(下露河). Korean Young Men`s Association(大韓靑年聯合會), Guanghandan( 光韓團), Korean Volunteer Army(朝鮮義勇隊), the Headquarters of the Korean Independence Army(光復軍司令部), the General Camp of the Korean Independence Army(光復軍總營), Tonggun-bu(統軍府), Jeongeui-bu(正義府), Korean Revolutionary Army (朝鮮革命軍) and Anti-Japanese Allied Army(抗日聯軍) were representative organisations in Dandong province. Korean educational system in dandong was organised primary school, secondary school, high school and adult education. The primary and secondary schools were founded in Kuandian, Fengcheng(鳳城) and Dandong where Koreans collectively resided; its curriculum was gradually under the influence of Japanese one. The adult education was begun as the Independence Army established night schools(Yahak) with propagating of letters and the idea of independence in 1920s. In Dandong after the Chinese Cultural Revolution(文化大革命), year-consecutive boarding schools were conducted, and Korean-Chinese secondary schools were opened. Besides the adult education was improved by newspapers and adult collages.
